It is configured and is connected by a communication line between FCS and OPS. With such a device, if an abnormality occurs in the plant, the OP
An alarm was generated via S to alert the operator and take necessary measures such as shutdown.

[Problems to be solved by the device]

However, since an alarm is provided for each generation unit of each internal instrument (for example, there is an input indicator and PID controller), the operator not only processes input units but also units such as reaction cans and batch pots. There was a request to monitor the alarm in. The present invention solves the above problems, and an object of the present invention is to provide an alarm generation device that can easily manage alarms on a device-by-device basis and can prevent frequent occurrence of alarms.

[Means for Solving the Problems]

A first invention for achieving such an object is to provide an internal instrument 10 for controlling a process variable, an alarm generator 20 provided one-to-one with the internal instrument for inputting an alarm signal generated by the internal instrument, It is provided for each device controlled by the internal instrument, and the alarm output from the alarm generator corresponding to this internal instrument is input.When an alarm is reported from any one of the alarm generators, an error occurs in the corresponding device unit. In an alarm generator that has a representative alarm unit 30 that displays that an alarm has occurred, when an alarm occurrence is displayed in a representative alarm unit, the alarm notification function of the internal instrument connected to the representative alarm unit is stopped. , When the alarms of all the internal instruments connected to the representative alarm section are released, the alarms of the internal instrument connected to the representative alarm section are released. The alarm bypass unit 50 for returning the alarm notification function is provided. A second invention for achieving such an object is, in the above-mentioned alarm generator, an alarm storage unit in which the degree of importance in the system is stored when an abnormality occurs in each internal instrument.
When an alarm is reported from the second internal instrument while the alarm caused by the first internal instrument is already displayed on 60 and a representative alarm section, the second alarm is referred to by the second internal instrument. If the degree of importance of the internal instrument is lower than the degree of importance of the first internal instrument, the alarm reception processing unit 70 that suppresses the representative alarm unit from issuing a new alarm due to the second internal instrument. Is provided.

[Action]

In the constituent elements of the first invention, the representative alarm unit displays an alarm for each device and expresses the alarm in a format that is familiar to the operator. In this case, if an alarm has already been notified by a certain device, alarm notifications may frequently occur from other internal meters in charge of this device. Therefore, when an alarm has already been notified by a certain device by the alarm bypass means, the alarm notification from other internal instruments in charge of this device is suppressed to prevent frequent occurrence of the alarm. In the second invention, the alarm storage unit stores the degree of importance of the internal instrument in the entire system for each control target, and the alarm reception processing unit, if an alarm has already been notified by a device, this device Even if there is an alarm notification from another internal instrument in charge, when the importance is lower, the alarm display is suppressed to prevent frequent alarms. However, when the alarm notification from another internal instrument is of higher importance, it is better to call the operator's attention, and an alarm is displayed.

【Example】

The present invention will be described below with reference to the drawings. FIG. 1 is a configuration block diagram showing an embodiment of the first device. In the figure, the internal instrument 10 is composed of a controller and an indicator for controlling a process variable, and detects a process variable such as a flow rate from a detection end, and operates an operating end such as a valve in comparison with a set value, Match the set value. The alarm generator 20 is provided one-to-one with the internal instrument 10.
Input the alarm signal of the internal instrument 10. The representative alarm unit 30 is provided for each device unit to which the internal instrument 10 is attached, and when an alarm occurs in any one of the alarm generators 20, a display to that effect is displayed on the display device 40 such as a CRT. . Here, a case is shown in which 16 internal meters 10 are connected to the representative alarm unit 30. This connection is specified in a process called engineering work according to the plant to be controlled. The alarm bypass unit 50 stops the alarm function of the internal instruments under its control for each control unit.
It is specified by the operator using the keyboard. Such representative alarm unit 30 and alarm bypass unit 50 are OPS
Often provided on the side. The operation of the apparatus thus configured will be described below. Fig. 2 is a flow chart showing the alarm status.
(A), (B) and (C) respectively correspond to the internal meters 1, 2 and 3, and (D) shows the representative alarm unit 30. When an alarm is generated in the internal instrument 1, the representative alarm unit 30 generates an alarm in response to the alarm. When an alarm continues to be generated in the internal instrument 2 while an alarm is being generated, the representative alarm unit 30 takes the pre-specified side of the following two measures. The first is to notify the new alarm occurrence in the representative alarm unit 30 and the second is to notify the representative alarm unit 30
Holds the alarm state and does not notify the occurrence of a new alarm. When the alarms of all the internal instruments are released, the representative alarm unit 30 returns to the normal state NR. Even if the internal instrument 3 independently generates an alarm or cancels the alarm, the representative alarm unit 30 follows and notifies the alarm. When the alarm bypass unit 50 gives an instruction to the internal instrument 10, the alarm generated by the internal instrument 10 is not notified to the operator, and only the alarm occurrence of the representative alarm unit 30 is notified. It will be a countermeasure. FIG. 3 is an explanatory view of the second embodiment of the present invention. Here, the representative alarm unit 30 suppresses the alarm occurrence notification according to the importance of the alarm. That is, for example, for the alarm on the internal instrument 10,
Attach importance such as medium and light. When an alarm occurs in another internal instrument 10 while the representative alarm unit 30 is generating an alarm, the following measures are taken. If the importance of the new alarm is higher than the alarm currently being generated, the new alarm is notified, and if the importance is lower, the alarm is not notified. FIG. 4 is a configuration block diagram showing an embodiment of the second invention. The alarm storage unit 60 stores the degree of importance of the entire system and the type of alarm corresponding to the abnormal state in the internal instrument 10. The type of alarm includes a CRT display, printing by a printer, an alarm sound using a buzzer, and a file for storing the internal instrument 10 that generated the alarm. When the alarm acceptance processing unit 70 accepts an alarm, the alarm acceptance processing unit 70 determines the importance of the internal instrument of the transmission source by referring to the alarm storage unit. Screen management unit 80
When the alarm reception processing unit 70 receives an alarm, the information of the internal instrument related to the alarm is displayed on the screen currently displayed, and when a plurality of alarms are received, the side of high importance is displayed. Display the internal instrument. In addition to this, printing, buzzer and file processing, which are other modes of the alarm, are performed. The operation of the apparatus thus configured will be described below. FIG. 5 shows an example of the CRT screen when an alarm occurs. When an alarm occurs, the buzzer notifies the alarm occurrence and displays the alarm at the top of the screen. Since this display is for each control unit, the operator may want to know detailed alarm information for each internal instrument 10. FIG. 6 is an explanatory view of the alarm window display, (A) shows alarm occurrence for each control unit, (B)
Is an alarm occurrence display for each internal instrument 10 related to the control unit. The operator who wants to know the details of the alarm operates the touch screen or the like to know the alarm information for each control unit. Also, if you want to know the recent occurrence of the alarm,
If you perform the same operation, the alarm panel is displayed. In this case, multi-window display is preferable in order to prevent the display of the currently displayed screen from disappearing. If you want to know the actual operation of the internal instrument 10, you need to call the control panel. FIG. 7 is an explanatory view of calling the control panel, (A) is an alarm panel, and (B) is an explanatory view of the control panel. By performing a touch screen operation on the alarm panel, the control panel including the instrument in which the most important alarm is generated can be called.

[Effect of device]

As described above, according to the first invention, by adopting the representative alarm unit 30, it is possible to manage the alarm on a device-by-device basis and to facilitate the operation management for each device. If the representative alarm unit is already displaying the alarm for each device in charge, the alarm bypass means 50 can be used to uniformly suppress alarm notifications from other internal instruments under the representative alarm unit to prevent frequent alarms. , Becomes less complicated for the operator. Further, as in the second invention, when the alarm storage unit 60 and the alarm acceptance processing unit 70 are already displaying the alarms for each device in charge of the representative alarm unit, the internal alarms from other internal instruments of low importance are displayed. When alarm notifications are suppressed from being displayed to the operator and alarm notifications from other highly important internal instruments are displayed to the operator, alarms necessary for the operator are notified while preventing frequent alarms. There is an effect that is done.
